sound problem asus f6v ATI RV620 Audio device

[Bram Kuijper]

Hi all,

I recently purchased a new laptop, an Asus F6v, on which I installed 
Ubuntu 8.10. Everything works perfectly except for sound, which does 
work perfectly under vista on the same machine. Does anybody know how 
to get the soundcard on this type of laptop working?

Given a recent posting on ubuntuforums, 
http://ubuntuforums.org/archive/index.php/t-1021477.html, I guess this 
soundcard is too new for ubuntu, so I guess I can better stick to 
vista for the time being?

ps: I have everything at my alsamixer unmuted, so that cannot cause 
the problem. Here are the specs of my soundcard. Any help is greatly 
appreciated.
